Lpi LPIC Exam 303: Security, version 3.0 Sample Questions (Q125-Q130):

NEW QUESTION # 125
In nftables, what is the purpose of a "base chain" as opposed to a "regular chain"?

A. A base chain is directly attached to a netfilter hook, such as input or forward, allowing it to receive packets from the kernel.
B. A base chain can only contain accept rules.
C. A base chain is used only for NAT rules.
D. There is no functional difference between base and regular chains.

Answer: A

Explanation:
A base chain in nftables is attached directly to one of the underlying netfilter hooks (such as prerouting, input, forward, output, or postrouting), which allows packets traversing the network stack at that point to be evaluated against the chain's rules. A regular chain, by contrast, is not attached to any hook and can only be reached when explicitly called (jumped or goto'd) from another chain, functioning similarly to a subroutine used for rule organization.

NEW QUESTION # 126
What is a DoS attack?

A. An attack that targets a specific user or organization
B. An attack that floods a network or server with traffic to make it unavailable
C. An attack that exploits a vulnerability in software
D. An attack that aims to steal sensitive information

Answer: B

NEW QUESTION # 127
Which of the following utilities is used to generate keys for DNSSEC?

A. rndc
B. delv
C. dnssec-dsfromkey
D. dnssec-keygen

Answer: D

NEW QUESTION # 128
Which IPsec mode encapsulates and protects the entire original IP packet, including its header, typically used for site-to-site VPN gateways?

A. Transport mode
B. Main mode
C. Aggressive mode
D. Tunnel mode

Answer: D

Explanation:
IPsec Tunnel mode encapsulates the entire original IP packet, including its original header, inside a new IP packet with a new header. This allows the original source and destination addresses to be hidden and enables IPsec to be used between gateways protecting entire private networks, such as in a site-to-site VPN. Transport mode, by contrast, only protects the payload of the original packet and retains the original IP header, making it more suitable for host-to-host communication.

NEW QUESTION # 129
What is the purpose of performing a TCP SYN scan (nmap -sS) rather than a full TCP connect scan (nmap -sT)?

A. A SYN scan does not complete the full TCP three-way handshake, making it faster and less likely to be logged by the target application.
B. A SYN scan can only be used against UDP services.
C. There is no difference between the two scan types.
D. A SYN scan is slower but more accurate than a connect scan.

Answer: A

Explanation:
A TCP SYN scan, sometimes called a "half-open" scan, sends a SYN packet and analyzes the response (SYN/ACK indicating an open port, or RST indicating a closed port) without completing the full three-way handshake by sending the final ACK. This makes SYN scans faster than full connect scans and less likely to be logged by the target application itself, since no full connection is ever established, though the scan may still be detected by network-based intrusion detection systems monitoring for unusual SYN patterns.
